RICHARD M. HOE, OF NEW YORK, N. Y.

VlVII'i'II-IOD 0F SECURING- TYPE ON ROTARYv BEDS.

Specification forming part of Letters Patent N o. 15,501, dated August 5, 1856; Reissued March 22, 1870, No. 3,893.

To all whom it may concern:

Be it known that I, RICHARD M. HOE, of the city, county, and State of New `York, have invented a new and Improved mode of Securing Type on Rotary Beds; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figs. l, 2, 3, .4 and 5, represent each a face view and end view of a segment of a revolving type bed with my improvement applied to it.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists in having the column rules provided with feet which are fitted in rabbets made transversely in the bed, the rabbets having keys inserted in them which fit over ledges or lips on the feet and secure the rules in the bed. y

To enable others skilled in the art to fully understand and construct my invention, I will proceed to describe it.

In the annexed drawings, A represents a type bed with its rabbeted grooves for receiving the feet a, of the column rules a, and for securing them in their proper places by means of the intermediate pieces b, which serve as keys and lit over the lips or ledges b', of the feet a, as shown clearly in the transverse section, Fig. l. The exterior surfaces of the keys Z), are flush with the surface of the bed A.

B, C, are two flat pieces of metal having` one straight edge, while the opposite edgesare cut so as to form a series of oblique or wedge-shaped projections c parallel one with the other, and operating recisely in the same manner as a simple we ge and gib. The only obj ect in cutting the edges of the metal strips B, C, into several projections as shown, being simply to reduce the motion or travel of the piece C, which is the wedge, to produce sulicient expansion for compressing the type. The gib piece B, is secured to the surface of the bed by means of feet projecting into the rabbeted grooves and being overlapped by the intermediate pieces or keys b, in the same manner as the column rules. The Wedge piece O, is prevented from falling out by the insertion of pins c projecting from the side in contact with the plate 02, and entering grooves cl, in said side plate, which grooves allow the pins sufficient travel, but confine the wedge to the bed.

D, E, are metal strips similar to B, C, respectively, except that instead of being Hat they are curved to conform to the surface of the bed. The wedge E being held inv its position in the same manner as the wedge C, but the gib D, is secured by mortises made in it opposite the ends of the column rules for the reception of tenons on the ends of said column rules, made for that purpose.

The foregoing description applies to all Y the gures, the only difference in them being in the manner of driving or drawing the wedges.

In Fig. 1, the wedges are drawn by means of screws underneath the surface of the bed, the nuts having projecting nibs traversing slots in the surface of the bed and extending into mortises in the ends of the wedge pieces E and C.

In Fig. 2, the wedges are pushed forward by screws f, f, being tapped into the end or side plate and their points being in contact with the rear ends of the wedges E and'C.

In Fig. 3, the wedges are drawn by the screws g, g being tapped in the point edges of the wedges after passing through holes in the side or end plate, the screws having shoulders on the outside to form the resistance.

In Fig. 4C, the wedges are urged forward by means of toothed pinions e, gearing into racks e, cut in the underside of the wedges having loose cranks or wrenches applied to the shafts of the pinions, also ratchets and pawls attached to the pinions to prevent the possibility of their moving back. In Fig. 5 the usual quoins cx, are employed and driven by a shooting stick. I believe this arrangement to be superior to 'all others known and in present use for the following' reasons, viz: Its durability, as it will last in good order as long as the bed itself. Its compactness, a feature often of the first importance. Its economy of the time required to lock up the form. Its perfect safety from the danger of breaking the end or side plates of the bed, which is frequently the case where screws are used, in consequence of the unequal strain imposed `on certain points by these methods, but which is obviated in this arrangement by the equal distribution of the whole pressure over the Whole surface of said plates, considerations of the most vital importance to the interests of the daily journal press.

I do not confine myself to any particular means for drawing or driving the Wedge plate or strips E, C, for various means and devices may be used for that purpose.

Having thus described my invention, What I claim as new and desire to secure by Let 0 ters Patent, is-

Securing or holding the column rules a',

in their places on the bed by means of thel feet a, Which fit in rabbeted grooves in the bed and have plates or keys Z), fitted over their lips or ledges ZJ', substantially as shown and described; and I claim this Whether the strips or plates B, C, D, E, are used or the usual quoins ax, or any other device or Wedging or binding the type and rules in the bed.
